Yellowing Plants

Hi im getting alot of burnt tips, which is not to bad, but alot of yellowing on all leafs on the left plant any ideas, i think there both coming near the end to harvest
i used bio bloom and grow and some eespom salts for the mag, shud i just flush next watering and wait for finish?
also lots purple stem

Could be N deficiency, too much nutes, locking out the N, what strength nutes are you at?

Flushing is always an option, but i still think its a deficiency of sorts... what medium are you growing in?

The purple could be the strain, what strain is it? or possible even to low of temps at "night" could cause purpling, i wouldnt worry about the purple, its the yellowing and the burnt tips to be concerned with...

some mediums the salt build up could be an issue...

good luck somebody else will have more info im sure

he is talking about red vein (looks purple in later stages)

something is off in the soil...............check the ph and flush it back to 6.5...........on your last 1/2 gallon mix it 3/4 str if u are later in the bloom make sure u use a good bloom......get a bottle of CalMg+ (this shit is great i use it in the flush water becuase it helps)

as the plant is ripening it becomes a whore for calmg and the PK out of NPK

The three elements promote plant growth in three different ways. In simple terms, these are:

• N – nitrogen: promotes the growth of leaves and vegetation[SUP][/SUP]
• P – phosphorus: promotes root and shoot growth
• K – potassium: promotes flowering and fruiting

look for something that is 2-4-4 or 3-4-4 and use that u will like the results

I have not used much nutrient tbh., i just added 2-3ml if biobloom thats all

your talking the general organics product line (the pic is of the feeding plan on the box )

biobud is 0.5-0.1-1
biobloom is 2-4-4

Hi I appreciate all replys , my bio bloom is 2.0-7-4 and bio grow 4.0 3.0 6.0 I only feed bio bloom 3ml per plant today and that is all these are bio bizz

also when all the pistols are brown is it time to harvest? about 40%-50% of them are

3mls to how much water ?


as for telling when it is done that is all on the strain (autos plants the leaves yellow up) other plants not sure have not done them yet so no info

its big bang auto flower the leaves are yellowing yeah but all pistols notbrown yet the the new flowers are coming with new pistol and starting to get crystals also i feed 3ml to bout 2-3 liters but after a few hours i noticed that there burning loads on the tips so i flushed both and just gonna leave them for now sure they will b ok till end prob couple weeks

the hairs will amber up during the dry/cure u do

yellowing is natural with autoflowers ..........it should be getting near the date they told u (68 days 75 days)........u will not be able to stop the yellowing the gentics of the plant are telling it is time to die ..............the lower set then the middle then the upper yellow..........this is a timing game now good luck


u need a microscope or a strong set of eyes/glass and look at the tricromes if they are all milky every were then the plant is done and at strongest thc
tricromes colors
clear..............not done........weak stuff
milky...............done highest thc.................more head high bussy active
amber.............over done thc degrading CBDs and other chemicals increasing...............more sofa locking

i look at it and try to get about 65 75% of them milky the other 25% still clear they will still mature as u dry ..........if u wait untill all milky before the 48 hours dark and then dry they will be more amber by the time u smoke it .................it is like timing when cooking a huge meal u under cook a little and let the power carry over finish up while it is resting ...............same thing here
